Problems solved by technology

The existing connection method is to arrange the bolts inside the column. Due to the limitation of space, the concentrated arrangement of the bolts leads to a small bending stiffness of the connection nodes, which cannot effectively transfer the bending moments of the nodes; in order to meet the requirements of the bearing capacity and stiffness of the connection nodes , it is necessary to install multiple bolts, and it is difficult to install and align; at the same time, for the convenience of installation, the column is designed as an L-shaped cross-section, which weakens the lateral rigidity of the structure
Therefore, the existing node connection methods cannot meet the requirements of higher node bearing capacity and stiffness

Abstract

The invention discloses a modular container building connection node. The modular container building connection node is used for connection of upper-portion and lower-portion container units. Each container unit is a cuboid structure formed by four frame beams, four container corner pieces and eight frame columns. Both the frame columns and the frame beams are constituted by cold bending type rectangle pipes. The frames columns and the frame beams are perpendicularly fixed to the container corner pieces. Tubular bolts are fixed to connecting ends of two adjacent upper and lower frame columns correspondingly. The tubular bolts penetrate through corresponding container corner pieces located below the tubular bolts and are in threaded connection with casing pipes. Two up-down adjacent container units are fixedly connected together through two symmetrical casing pipes. Each connection node is connected in a threaded manner only through a set of tubular bolt and casing pipe. Through threaded connection between the tubular bolts and the casing pipes, pre-tightening force can be applied, reliability and tightness of connection can be reinforced, rigid connection can be formed by connecting nodes, bending moment and shearing force can be transmitted simultaneously, and the bearing capacity and rigidity of the modular container building connection node are improved conspicuously.

Description

technical field [0001] The invention relates to the field of modular container building connection nodes, in particular to a modular container building connection node. Background technique [0002] Prefabricated houses suitable for container transportation are often called modular buildings, box buildings or box buildings. The prefabricated houses transported by containers are composed of container bottom panels, wall panels, columns, container top panels and connectors, which are transported to the site for installation after streamlined production in the factory. Compared with traditional construction methods such as cast-in-place reinforced concrete structures and masonry structures, prefabricated houses transported by containers have high engineering quality reliability, short construction period, environmental protection and energy saving, low construction risk, and the production process is not affected by the weather, etc. Advantages, and can be moved, easy to disas...
